Additional ranking criteria

The RTP of games and its importance

RTP works by averaging out the payout rates and the bets that are made over many thousands of games. This means that we were not able to calculate the RTP rate of the games that were given by the casinos because of how big the variance would be. It would skew our results. To top this off, there are complex calculations that you must perform if you are to find out the true RTP rate. You need to also know how probable it is for a particular symbol to occur at various points in the game. This is not information that you can easily find. However, this information is available to the regulators. They perform in-depth analysis on the games and their RTP rates.

Now, perhaps you want to know how we have gotten our results in our testings. Most of the casino websites provide the RTP information for every game that they feature. So, we have performed analysis on the numbers and we made a list on the range of the return to player rates for the casino’s games in their respective categories. However, this is not as simple as it sounds – it takes more than just picking out the highest and lowest figures and sorting them out. This can mislead you. We could take the slots as an example. If you analyze the RTP of over 300 of these games, then you will likely see results for the RTP from 80% to 99%. But there may be a few games with RTP rate of below 90% and many games with an RTP of above 95%. So, if you remove the below 80% games it will give you a clearer picture of the current RTP numbers in the casino.

The payout percentage is a number that represents the money that it pays to the players in proportion to all of the deposits. As an example, if a casino should get £1 million in deposits and if it then pays off £995,500 to the players, then the payout percentage will be 99.55%. However, not all of the casino operators publish these numbers. The Return To Player category is very similar to the payout percentage – the only difference is that the RTP is usually specific for the slot games. One particular slot game may have a lower RTP than another – this will make the first game less attractive in the eyes of gamblers.

Software check for games for the best performance

We have assessed many different elements of casino websites, yet there is still something missing here. The factor that we have neglected to mention up until now is the minimum requirements. So, we have decided to add to our lists the minimum hardware requirements – and also the software requirements, such as plugins and browsers that you may need for playing the games. Most online casinos exhibit all of this information on their websites and we have used this information in order to give you what technical specifications you will need to fulfill in order to play the games. You will find this information in each of the individual reviews. If a particular website didn’t share any information in the minimum requirements – then we gave a shot at finding the minimum requirements by testing with our own equipment. This wasn’t an easy thing to do – we needed to use very old machines in order to reach the lowest possible requirements. In the above cases, we managed to get additional details about the minimum requirements of certain games.

Finding out the best payment methods

Since we need to provide accurate information about the payments, we have decided to create lists of the details of each particular casino website that we review. We also did an audit – we tried paying and withdrawing money with a variety of different payment methods at different casino websites. What this allowed us to do is to ascertain whether the casinos were providing accurate data and information about the payment methods that they support. If you want to do withdrawals, however, you will need to undergo an ID check at the behest of the casino. For some casinos, the casino would have to perform an ID check before you even make your first deposit. We have tested both the payments and the identification processes at different casinos. This ensures that the information that the casino provides on these processes is correct and up to date.
